Hello all, I'm looking to buy 4-8 controllers for some couch coop games and haven't found any clear winners so far. I'm leaning 2.4Ghz as I've heard problems about bluetooth controllers disconnecting on the steam deck and always appreciate less latency. I also don't need any fancy features like gyro or touchpads, just the generic xbox-like style would be great. Also my last problem is that every one I've found requires a dongle per controller, to which I'm wondering if 4-8 dongles next to each other would cause interference?

In essence: if anyone has recommendations on controllers for couch coop games on the steam deck where the main priority is connection stability, it'd be much appreciated!
